Taking measurements in a scramjet engine is particularly challenging because of the harsh testing environment. Any probe inserted in the flow would generate shock waves, strongly perturbing the flow. Coherent Anti-Stokes Raman spectroscopy (CARS) is a non-intrusive laser-based measurement technique that has been implemented successfully to measure temperature and species concentrations in ducted scramjet engines.
